The GetAcpiTable() function returns a pointer to a buffer containing the ACPI table associated\r
with the Index that was input. The following structures are not considered elements in the list of\r
ACPI tables:\r
Version is updated with a bit map containing all the versions of ACPI of which the table is a\r
member. For tables installed via the EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() interface,\r
the function returns the value of EFI_ACPI_STD_PROTOCOL.AcpiVersion.\r
